  • Q1
    The model below shows two continental plates. The folded mountains in this model form at which type of plate boundary?
    Question Image
    Divergent boundary
    Transform boundary
    Subduction boundary
    Convergent boundary
  • Q2
    The thick black lines on the map below show the locations of mid-ocean ridges. Which geologic feature is most likely to form at a mid-ocean ridge?
    Question Image
  • Q3
    The image shows a plate boundary. Arrows have been added to indicate the movement of the plates. What plate boundary feature is also shown?
    Question Image
    A valley forming at an active divergent boundary
    A fault forming at an active transform boundary
    A ridge formed by an inactive convergent boundary
    A volcano formed by an active transform boundary
  • Q4
    The map below shows the locations of four active volcanoes in the Caribbean Sea. What do these volcanoes indicate about plate tectonics in the region?
    Question Image
    The volcanoes form a line, indicating a diverging plate boundary.
    The volcanoes form an island arc, indicating a converging plate boundary.
    Two plates are moving apart, creating new seafloor
    Two plates are moving past each other, causing faulting and magma formation.
  • Q5
    Rift valleys can form when fractures in Earth’s crust widen. The valley walls slowly move at a rate of only a few millimeters a year. Which of these best describes the type of tectonic activity that forms rift valleys?
    Rift valleys form where two plates move away from each other.
    Rift valleys form where a continental plate moves under an oceanic plate.
    Rift valleys form where a plate slides horizontally past another plate.
    Rift valleys form where an oceanic plate moves under another oceanic plate.
